The shot clock is running. A decent shot now beats a perfect one after the buzzer.

A decent option taken now usually beats a perfect one that arrives after the window closed. Time is part of every decision rather than a neutral background to it, and while you refine, the situation keeps moving underneath you. Waiting is itself a choice, it just never announces itself as one.

Give the next medium decision a deadline you actually keep, even an arbitrary one. Choose at the buzzer with whatever you have got. Most choices this size can be corrected later, while the timing is the part you cannot get back.
